Pie Baking Assist Apparatus Resisting Crust Deformation

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

During blind baking of pie crusts, the dough tends to expand and deform, becoming detached from the non-stick coated surface of the pie pan, leading to undesired distortion and shrinkage of the shell.

Innovation Solution

A baking assist apparatus featuring a passive resistance band made of a heat-resistant, flexible material is used. The band is positioned against the inward-facing surface of the pie crust dough wall, applying a compressive force to maintain the shape of the dough against the rigid pie pan walls, thereby resisting deformation during baking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a non-stick coating is applied to the pie pan surface, then the pie crust can be easily removed after baking, but the crust becomes detached and deformed during the baking process

Engineering Contradiction:

Improveease of pie crust removalVSAvoidstability of pie crust shape

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

A release paper or parchment paper is placed between the pie crust and the non-stick coated pan surface. This intermediary layer prevents direct contact between the crust and pan, eliminating the detachment problem while maintaining easy removal capability. The release paper acts as a mediator that resolves the contradiction between non-stick properties and shape stability during baking.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If the pie crust is allowed to expand freely during baking, then the dough becomes fluffy and baked, but the crust deforms and shrinks towards the center

Engineering Contradiction:

Improvefluffiness of baked crustVSAvoidshape retention of pie crust

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

Baking weights or pie weights are placed on top of the pie crust during blind baking. These weights apply downward pressure that counteracts the upward expansion force of the rising dough, preventing deformation and shrinkage while still allowing controlled fluffiness. The weights provide a counterbalancing force that maintains shape stability during the baking process.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The pie crust is pre-chilled or pre-freezed before baking to reduce its elasticity and prevent excessive expansion. This preliminary action stabilizes the dough structure before the baking process begins, allowing the crust to maintain its shape while still achieving the desired fluffiness during baking.

Inventive Principle:

Principle #10Preliminary action

3Strength

If the sidewall of the pie pan is rigid, then the pie crust maintains structural support, but the crust becomes detached from the pan surface

Engineering Contradiction:

Improvestructural support of pie panVSAvoidattachment of pie crust to pan

Core Design Contradiction:

StrengthVSStability of the object's composition

Solution Approach 1:

A release paper or parchment paper is placed between the pie crust and the rigid pan surface. This intermediary layer prevents direct attachment while maintaining structural support from the rigid pan walls. The release paper eliminates the harmful attachment effect while preserving the beneficial structural support function of the rigid sidewalls.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Baking assist apparatus has a passive resistance band formed of a continuous, thin-walled, flexible, elongate web element formed of a heat resistant material. An outward-facing surface of the web element is configured for positioning against an inward-facing surface of a wall of an unbaked pie crust so as to impart thereto a manually applied compressive force causing compression of the pie crust wall against a pie pan rigid peripheral wall such that the pie crust wall adopts the shape thereof and so as to adopt a selected thickness; and one or both edges of the web element are configured for impressing into a surface of the unbaked pie crust juxtaposed to the pie crust wall so as to assist in anchoring the web element and fixating the pie crust dough wall so as resist deformation during baking.
